Degree sends interval packet column to tested end, RI2=RO1；
SS4) be tested end by receiving step SS3) send interval packet column count packet receiving speed RO2, to RI2/RO2-1
Judged, if RI2/RO2- 1≤measuring accuracy Ac, then determine RI2/RO2- 1 in agreement accuracy rating, enters step SS7)；
If RI2/RO2- 1 > measuring accuracy Ac, then determine RI2/RO2- 1 not in agreement accuracy rating, enters step SS5)；
SS5) it is tested packet receiving speed RO end calculated step SS4)2It is sent to test lead, test lead passes through public affairs
FormulaCalculate RI3, test lead is with RI3Speed sends interval packet column to tested
End；
SS6) be tested end by receiving step SS5) send interval packet column count packet receiving speed RO3；
SS7 it) is tested end and available bandwidth is calculated by band width in physical and packet receiving speed, speed of giving out a contract for a project；
When testing downlink available bandwidth, test lead is server end, and being tested end is client, testing uplink available bandwidth
When, test lead is client, and being tested end is server end.
What available bandwidth testing scheme of the present invention was sent is out-of-sequence packet column, when reception, be only concerned first packet received and
The interval time of the last one packet, therefore will not be interfered by out-of-order and packet loss.And the present invention at most only tests three times, to the time and

The wide hundred times of unified test test strip.And the present invention is small to the customer impact that tests the speed, rate accuracy is high.Because present invention uses small flows
Speed testing mode, and solve the problems, such as very well big concurrent, due to testing the speed, flow consumption is considerably less, and time-consuming also very short,
Therefore will not have an impact to user.
This system supports broadband, mobile network to test the speed simultaneously, and this system tests the speed can assess band width in physical and available band
Width accurately tests the speed to the leaky bucket model of bandwidth operator, token bucket mode speed limit.
